“What these older films have in common is that they have a really suspenseful, stripped down narrative but the actions become metaphors for something else,” Jonas Cuaron said. “When we were doing the script we were more referencing like space documentaries. I think a lot of what we were trying to achieve was realistic like a space documentary gone wrong in space.”

The film is a first foray into space for both helmer Cuaron (and he added, his last) and Sandra Bullock, who with co-star George Clooney, went through vigorous filming.

Cuaron said “trying to make these guys float” was the most challenging part of filming ‘Gravity.’ “I was like, ‘Float, George. C’mon, float!’ I don’t know which acting school these guys went to that they don’t know how to float.”

“They tried to kill me on a daily basis, George and Alfonso, but they were obviously unsuccessful,” Bullock said. “And they will probably try to kill me again tonight, but they will be unsuccessful. They will not take me down.”

“Working with Sandy was the most difficult because she’s not nice,” Clooney joked, but then said, “Just physically, [the harness] was uncomfortable. Much less for me than Sandy because she did it a lot longer, but you know, it’s not fun hanging in there the way you do for a long time.”

If Clooney were to ever venture to the “final frontier,” there’s only one “thing” he’d like to bring with him.

“I would bring, although, you don’t want to call it a possession because he’ll get mad, but I would bring my dog Einstein, because my dog Einstein and I travel everywhere now. He’s good one – he’s a keeper,” Clooney said.

“I would never go to space,” Bullock said on the contrary. “I would never go to space, but I say if my son, when I’m 80 years old, says, ‘Mom, I want to do this,’ and I know that he’s a big boy, and I no longer have to worry, I would go up there for him. That’s the only person who can get me up there.”
